Description

Technical Field

[0001] This utility model belongs to the technical field of solid waste crushing equipment, and in particular relates to a multi-stage solid waste crushing device. Background Technology

[0002] The treatment and resource utilization of industrial solid waste is an important issue in the field of environmental protection. Among them, crushing, as a key pretreatment step, directly affects the efficiency of subsequent sorting, recycling, and disposal. Jaw crushers are widely used in the coarse crushing stage of industrial solid waste due to their simple structure and reliable operation.

[0003] However, existing solid waste treatment equipment based on the jaw crusher principle still has many shortcomings in practical applications. First, traditional crushing equipment usually only has a single crushing function. The crushed material needs to be transferred manually or by a separate conveyor to a separate screening machine for particle size separation. For unqualified large-diameter materials, they need to be collected again and put back into the crusher for secondary crushing. This segmented "crushing-screening-returning" process not only results in dispersed equipment layout and large footprint, but also requires multiple material transfers, leading to a cumbersome overall process flow, high energy consumption, and low production efficiency.

[0004] Secondly, in order to achieve the linkage between crushing and screening, some improved equipment will choose to configure a separate drive motor for the screening mechanism. Although this approach achieves functional integration, it adds an extra power source and control system, resulting in a significant increase in equipment manufacturing and operation and maintenance costs. Furthermore, the coordinated control between multiple motors is complex, and asynchronous power can easily lead to material accumulation at the interface or the equipment running idle.

[0005] Therefore, there is an urgent need for a new type of multi-stage solid waste crushing device that can highly integrate crushing, screening and automatic return of unqualified materials, and use a single power source to drive multiple actions, in order to solve the problems of high energy consumption, large footprint, discontinuous process flow and low degree of automation in existing technologies. Utility Model Content

[0006] This utility model provides a multi-stage crushing device for solid waste, which aims to solve the problems of high energy consumption, large footprint, discontinuous process flow and low degree of automation of current equipment.

[0007] This utility model is implemented as follows: a multi-stage solid waste crushing device, comprising: Support frame; The outer frame is fixedly installed on the top of the support frame; A stationary jaw is fixedly installed inside the outer frame; A movable jaw is installed inside the outer frame and cooperates with the stationary jaw, forming a crushing cavity between the movable jaw and the stationary jaw; A drive motor is fixedly installed at the top of the support frame; The drive component, located between the drive motor and the outer frame, can drive the moving jaw to reciprocate under the drive of the drive motor, thereby crushing the material in cooperation with the stationary jaw. The screening assembly, located inside the support frame and below the moving jaw and stationary jaw, is used to screen and convey materials crushed by the moving jaw and stationary jaw. The linkage mechanism, which is set between the screening component and the drive motor, can drive the driving component through the drive motor and the screening component through the linkage mechanism at the same time. The screw conveyor, located on one side of the support frame, is used to transport a portion of the material that has been screened by the screening component.

[0008] Preferably, the screening assembly includes a screening frame disposed below the moving jaw and the stationary jaw, and sliding plates are fixedly connected to both outer walls of the screening frame.

[0009] Preferably, the support frame has a slide rail on its inner side, the slide plate is slidably disposed on the inner side of the slide rail, and the upper and lower outer walls of the slide plate are rotatably fitted with ball bearings.

[0010] Preferably, the screening assembly further includes a receiving frame, the tops of the two side walls of the receiving frame being fixedly connected to the bottoms of the two slide plates respectively.

[0011] Preferably, both the receiving frame and the screening frame are inclined, and the inclination directions of the receiving frame and the screening frame are opposite.

[0012] Preferably, the linkage mechanism includes a bearing fixedly connected to the top of the support frame, a shaft is rotatably sleeved on the inner side of the bearing, and one end of the shaft is fixedly connected to the output shaft of the drive motor.

[0013] Preferably, a transmission component is provided on the side of the shaft away from the drive motor. The transmission component includes two sprockets and a chain that is connected between the two sprockets. A rotating rod is rotatably connected to the outer wall of the support frame. The two sprockets are respectively fixedly sleeved on the outer wall of the shaft and the rotating rod.

[0014] Preferably, a turntable is fixedly connected to one end of the rotating rod, a push-pull column is eccentrically fixed to the outer wall of the turntable, a rotating block is rotatably sleeved on the outer wall of the push-pull column, a connecting rod is fixedly connected to one end of the rotating block, and one end of the connecting rod is hinged to the screening frame.

[0015] Preferably, the screw conveyor includes a fixed plate fixed to the side wall of the support frame, a material collection frame fixed to the top of the fixed plate, a vertical pipe fixedly connected to one side of the material collection frame, a screw body rotatably connected to the inside of the vertical pipe, and a rotary motor for driving the screw body to rotate fixedly installed at the top of the vertical pipe.

[0016] Preferably, a guide pipe is fixedly connected to the upper side of the vertical tube, and the end of the guide pipe away from the vertical tube is located on the upper side of the gap between the moving jaw and the stationary jaw.

[0017] Compared with related technologies, the multi-stage solid waste crushing device provided by this utility model has the following beneficial effects: 1. Crushing-Screening Linkage System: Through a linkage mechanism, a single drive motor simultaneously drives the crushing component (moving jaw) and the screening assembly (screening frame). Specifically, the output shaft of the drive motor transmits power to the turntable via a shaft, sprocket, and chain mechanism, which is then converted into the reciprocating linear motion of the screening frame via push-pull columns and connecting rods. This design abandons the traditional approach of configuring a separate motor for the screening function, simplifies the transmission structure, and reduces the manufacturing cost and energy consumption of the equipment from the source. Because the power source is the same, the crushing and screening actions operate synchronously, avoiding material accumulation or equipment idling caused by asynchronous start-stop, further improving energy efficiency and conforming to the green and environmentally friendly equipment design concept.

[0018] 2. High-efficiency sorting and conveying structure: The screening component adopts a unique layout where both the screening screen frame and the receiving frame are inclined in opposite directions. Driven by a linkage mechanism, they oscillate synchronously, but because their inclination directions are opposite, qualified and unqualified materials can automatically move and converge in different directions. This structure utilizes the material's own weight and the movement of the screen body to achieve automatic, continuous separation and directional conveying of qualified and unqualified products. It eliminates the need for additional power conveying equipment for initial sorting, resulting in high sorting efficiency, a smooth process, effectively reducing the risk of material blockage, and creating conditions for subsequent independent processing (such as discharging qualified materials and returning unqualified materials).

[0019] 3. Closed-loop processing flow: After initial crushing by the moving and stationary jaws, the material falls onto the screening frame for sieving. Unqualified material is automatically returned to the crushing chamber by a screw conveyor for secondary crushing; qualified material is collected and output by the receiving frame. The entire process is completed continuously and automatically within a single piece of equipment. This closed-loop design solves the problem of traditional crushing equipment requiring intermediate transfer or manual intervention for secondary crushing, greatly improving overall processing efficiency. By ensuring that all material reaches the qualified particle size before discharge, the uniformity and quality of the final product are significantly improved (e.g., the impurity content of aggregates can be effectively reduced), laying a good foundation for subsequent resource utilization (such as the production of recycled aggregates).

[0024] Example 1 A preferred embodiment of the multi-stage solid waste crushing device provided by this utility model is, for example... Figures 1 to 4As shown: A multi-stage solid waste crushing device includes a support frame 1; an outer frame 9 fixedly installed on the top of the support frame 1; a stationary jaw 8 fixedly installed inside the outer frame 9; a movable jaw 7 movably installed inside the outer frame 9 and cooperating with the stationary jaw 8, forming a crushing chamber between the movable jaw 7 and the stationary jaw 8; a drive motor 4 fixedly installed on the top of the support frame 1; a drive component 6 located between the drive motor 4 and the outer frame 9, which, under the drive of the drive motor 4, can drive the movable jaw 7 to reciprocate, thereby crushing the material in cooperation with the stationary jaw 8; a screening component 3 located inside the support frame 1 and below the movable jaw 7 and the stationary jaw 8, used for screening and conveying the material crushed by the movable jaw 7 and the stationary jaw 8; and a linkage mechanism 5 located between the screening component 3 and the drive motor 4, which, while driving the drive component 6 through the drive motor 4, can also drive the screening component 3 through the linkage mechanism 5.

[0025] In a further preferred embodiment of this utility model, the screening assembly 3 includes a screening frame 302 disposed below the moving jaw 7 and the stationary jaw 8, with sliding plates 303 fixedly connected to both outer walls of the screening frame 302. A slide rail 101 is provided inside the support frame 1, and the sliding plate 303 is slidably disposed inside the slide rail 101. Ball bearings 304 are rotatably fitted onto the upper and lower outer walls of the sliding plate 303. The screening assembly 3 also includes a receiving frame 301, with the tops of both side walls of the receiving frame 301 fixedly connected to the bottoms of the two sliding plates 303. Both the receiving frame 301 and the screening frame 302 are inclined, and their inclination directions are opposite.

[0026] In a further preferred embodiment of this utility model, the linkage mechanism 5 includes a bearing seat 501 fixedly connected to the top of the support frame 1. A shaft rod 502 is rotatably sleeved on the inner side of the bearing seat 501, and one end of the shaft rod 502 is fixedly connected to the output shaft of the drive motor 4. A transmission component is provided on the side of the shaft rod 502 away from the drive motor 4. The transmission component includes two sprockets 503 and a chain 504 connecting the two sprockets 503. A rotating rod 505 is rotatably connected to the outer wall of the support frame 1. The two sprockets 503 are respectively fixedly sleeved on the outer wall of the shaft rod 502 and the rotating rod 505. A turntable 509 is fixedly connected to one end of the rotating rod 505. A push-pull column 506 is eccentrically fixed to the outer wall of the turntable 509. A rotating block 507 is rotatably sleeved on the outer wall of the push-pull column 506. A connecting rod 508 is fixedly connected to one end of the rotating block 507, and one end of the connecting rod 508 is hinged to the screening frame 302.

[0027] In this embodiment, during operation, the industrial solid waste to be crushed is thrown between the moving jaw 7 and the stationary jaw 8. The power is turned on, and the drive motor 4 is started. The drive motor 4 drives the moving jaw 7 through the drive component 6, causing the moving jaw 7 to continuously impact and crush the material falling between the moving jaw 7 and the stationary jaw 8. It is understood by those skilled in the art that the crushing principle and the basic structure of the drive component 6 are well-known and belong to the prior art, and will not be elaborated further here. The initially crushed material intermittently falls from the bottom of the moving jaw 7 and the stationary jaw 8 onto the inclined screening frame 302. During this process, the output shaft of the drive motor 4 drives the shaft 502 to rotate. Under the action of the chain 504, the shaft 502 drives two sprockets 503 to rotate synchronously. One of the sprockets 503 drives the rotating rod 505 to rotate, which in turn drives the turntable 509 to rotate. The turntable 509 drives the push-pull column 506 to revolve. The rotating block 507 on the push-pull column 506 affects the connecting rod 50. 8. The connecting rod 508 is pushed and pulled back and forth, causing the screening frame 302 to be pushed and pulled back and forth. During this process, the sliding plate 303 slides smoothly inside the slide rail 101 through the ball bearings 304. Under the guidance and limitation of the sliding plate 303 and the slide rail 101, the screening frame 302 can be swayed smoothly to screen the material falling on it. The material with qualified particle size falls through the mesh of the screening frame 302 into the receiving frame 301, while the material with unqualified particle size remains on the surface of the screening frame 302 and moves to its lower end.

[0028] In this embodiment, since the tops of both sides of the receiving frame 301 are fixed to the bottoms of the two sliding plates 303, the swaying of the screening frame 302 can also cause the receiving frame 301 to sway. Because the inclination directions of the receiving frame 301 and the screening frame 302 are opposite, qualified and unqualified materials can be collected and output in opposite directions. The unqualified material remaining after screening by the screening frame 302 is returned to the area between the moving jaw 7 and the stationary jaw 8 via the screw conveyor 2 for further crushing. The qualified material collected by the receiving frame 301 can be output as a finished product or enter the next round of fine crushing, for example, through fine crushing in an impact crusher or a dedicated grinding mechanism.

[0029] Example 2 Based on Example 1, a preferred embodiment of the multi-stage solid waste crushing device provided by this utility model is, for example... Figures 1 to 4 As shown: The solid waste multi-stage crushing device also includes a screw conveyor 2 installed on one side of the support frame 1, which is used to transport part of the material that has been screened by the screening component 3.

[0030] In a further preferred embodiment of the present invention, the screw conveyor 2 includes a fixed plate 201 fixedly connected to the side wall of the support frame 1, a material collection frame 202 fixedly connected to the top of the fixed plate 201, a vertical pipe 203 fixedly connected to one side of the material collection frame 202, a screw body 204 rotatably connected to the inner side of the vertical pipe 203, and a rotary motor 206 for driving the screw body 204 to rotate fixedly installed at the top of the vertical pipe 203.

[0031] In a further preferred embodiment of the present invention, a guide pipe 205 is fixedly connected to the upper side of the vertical pipe 203, and the end of the guide pipe 205 away from the vertical pipe 203 is disposed on the upper side of the gap between the moving jaw 7 and the stationary jaw 8.

[0032] In this embodiment, the initially crushed and unqualified material falling from the screening frame 302 is collected in the collection frame 202. At this time, the rotary motor 206 is started, and the rotary motor 206 drives the spiral 204 to rotate. The spiral 204 conveys the material located inside the collection frame 202 upwards again. When it is conveyed to the guide pipe 205, it is conveyed back to the inner side of the outer frame 9 through the guide pipe 205, and then further crushed by the moving jaw 7 and the stationary jaw 8.
